Le N311 ECM is a specific type of cylindrical roller bearing. Ecco una ripartizione delle sue caratteristiche e specifiche principali:
1. Tipo di cuscinetto: Cuscinetto a rulli cilindrici
- I cuscinetti a rulli cilindrici sono progettati per gestire carichi radiali elevati e carichi assiali moderati. They have high rigidity and are suitable for high-speed applications.
2. Designazione del cuscinetto: N311 ECM
- N: Indicates the bearing type. In this case, “N” refers to a cylindrical roller bearing with no flanges on the outer ring, allowing the inner ring to move axially relative to the outer ring.
- 311: This is the size designation. The first digit (“3”) represents the series (medium series), and the last two digits (“11”) indicate the bore diameter. For “11,” the bore diameter is calculated as 11 x 5 = 55 millimetro.
- ECM: This suffix indicates specific design features:
- EC: Optimized internal design with more and/or larger rollers, providing higher load capacity.
- M: Indicates the bearing uses brass (copper alloy) cage, which is suitable for high-speed applications and offers better durability.
3. Dimensioni:
- Diametro foro (d): 55 millimetro
- Diametro esterno (D): 120 millimetro
- Larghezza (B): 29 millimetro
4. Valutazioni del carico:
- Coefficiente di carico dinamico (C): Typically around 108 Kn (exact value depends on the manufacturer).
- Coefficiente di carico statico (C0): Typically around 102 Kn (exact value depends on the manufacturer).
5. Applicazioni:
- Cylindrical roller bearings like the N311 ECM are commonly used in:
- Riduttori
- Motori elettrici
- Macchine utensili
- Industrial machinery
- Applications requiring high radial load capacity and moderate axial displacement.
6. Caratteristiche principali:
- Elevata capacità di carico radiale
- Suitable for high-speed operations
- Brass cage for durability and high-speed performance
- Allows axial displacement of the shaft relative to the housing
7. Manufacturer Variations:
- The exact specifications (Coefficienti di carico, Tolleranze, etc.) may vary slightly depending on the manufacturer (ad es., SKF, NSK, FROCIO, Timken). Fare sempre riferimento alla scheda tecnica del produttore per dettagli precisi.
